Hi all, according to the offical D-Link documentation, my DCS-920 should show up as a media source on my DSM-750 via Media Lounge - but it doesn't. UPNP is working because I can see the DCS-920 show up on my other computers as a web link. How can I make it show up as a media source on my DSM-750? It's the reason I bought the thing in the first place....Here's hoping a shout in the dark is fruitful!
